There are parrots in New Zealand called keas that fancy something a little more interesting than the usual fruit and nuts they eat meat. To hunt, birds need super-senses and great skill. Great grey owls in North America can listen in super-stereo to the movements and noises made by lemmings hidden away under a thick blanket by snow. In Europe, kestrels are a familiar sight hovering over motorway verges. Using their ultra-violet vision, kestrels position themselves over areas where voles have marked their tracks with drops of urine, which is very conspicuous in ultra-violet. In the rainforests of Trinidad, David Attenborough finds a bird with an acute sense of smell. Attenborough buries a piece of meat under some leaves and twigs and retreats to a distant vantage point.
